We will anyway remove the platform data part soon. If you say I can
resend it again.
I think that the requirement for platform data on DT-enabled systems
should be removed before this series get merged, because there are already
patches being worked on to remove auxdata tables (common clock framework
support by Thomas Abraham).
Next is to add support for 4210, 4x12 and Exynos5 (patches were sent
by vivek Gautam already). Not only s3c-hsotg but ehci, ohci and dwc
will start using phy driver.
This will remove phy related platform data passed to these drivers and...
Adding next auxdata entry (containing platform data that must be provided)
would make them depend on phy platform data removal patch, which would
complicate things.
s3c-hsotg platform data is also passing "is_osc" (Clock source info)
and "dma" (dma mode info) from platform_data. IT seems they both are
not used as on now. May be Lukasz can tell if we can move that to
config option and get rid of s3c-hsotg_plat completely.

Once that is done only AUXDATA entry, which will be remaining, will be
that of phy driver and I understand that we have to work towards
removal of that as well but I guess this is a good first step towards
the goal.
Best regards,
